Product details
Overview
MSP430F5436AIZQWT from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 192 KB flash, 16 KB RAM, 12-bit ADC (14 external + 2 internal channels), four USCI modules (2 UART/IrDA/SPI + 2 I²C/SPI), three 16-bit timers (TA0/TA1/TB0), RTC, hardware multiplier, and DMA - deployed in battery-powered sensor nodes and portable meters.
For engineers reviewing the MSP430F5436AIZQWT datasheet, MSP430F5436AIZQWT pinout, MSP430F5436AIZQWT application, or MSP430F5436AIZQWT equivalent, key selection criteria include standby current (1.7 µA in LPM3), 113-pin MicroStar Junior BGA package, 87 GPIOs, 25-MHz max system clock, and integrated LDO with programmable core voltage.
Technical Context
The MSP430F5436AIZQWT implements a unified clock system with FLL stabilization, dual crystal support (32-kHz XT1 and up to 32-MHz XT2), VLO and REFO internal sources, and dynamic clock gating across MCLK/SMCLK/ACLK domains. Its power management includes SVM/SVS supervision, brownout reset, and LDO regulation with programmable VCORE.
Peripherals are tightly coupled to the CPUXV2 core via a 16-bit address/data bus; the 12-bit ADC12_A supports autoscan, sample-and-hold, and internal reference, while USCI modules provide independent UART/IrDA/SPI and I²C operation with configurable baud rates and clock sources.

FAQ
What is the maximum operating frequency of the MSP430F5436AIZQWT?
The MSP430F5436AIZQWT supports a maximum system clock frequency of 25 MHz, achieved via its digitally controlled oscillator (DCO) locked to an external crystal or reference using the integrated FLL. This frequency enables high-speed serial communication, fast ADC sampling at 200 ksps, and responsive real-time control without external clock multiplication circuitry. The device maintains full functionality across its 1.8–3.6 V supply range at this speed.
Does the MSP430F5436AIZQWT include an integrated DC-DC converter?
No, the MSP430F5436AIZQWT does not include an integrated DC-DC converter. It features a fully integrated low-dropout regulator (LDO) that provides programmable core voltage (VCORE) from 1.8 V to 3.0 V, but requires an external input supply (DVCC) within the 1.8–3.6 V range. The LDO ensures stable core operation and low-noise analog performance, while external DC-DC conversion must be implemented upstream if higher efficiency is needed for wide-input-voltage applications.
How many analog input channels does the ADC on the MSP430F5436AIZQWT support?
The MSP430F5436AIZQWT integrates a 12-bit ADC12_A module supporting 14 external analog input channels (A0–A15, excluding A10/A11) and 2 internal channels (temperature sensor and VCC/2). This configuration is confirmed in the device comparison table and functional block diagram for the MSP430F5436A variant. Channel mapping is fixed per pin assignment (e.g., P6.4 = A4, P7.7 = A15), and autoscan mode enables sequential conversion without CPU intervention.
Is the MSP430F5436AIZQWT pin-compatible with other devices in the MSP430F543xA family?
Yes, the MSP430F5436AIZQWT shares identical pinout and signal mapping with MSP430F5438AIZQW and MSP430F5419AIZQW in the 113-ball MicroStar Junior BGA (ZQW) package, as verified in Figure 7-3 and Table 7-1 of the datasheet. All three devices use the same ball grid, I/O function assignments, and power/ground ball locations - enabling direct PCB reuse across flash-size variants within this package group.
What debug interface does the MSP430F5436AIZQWT support?
The MSP430F5436AIZQWT supports the two-wire Spy-Bi-Wire (SBW) interface via the RST/NMI/SBWTDIO and TEST/SBWTCK pins, compatible with TI's MSP-FET and LaunchPad debuggers. It also supports full 4-wire JTAG through PJ.0–PJ.3 for boundary scan and advanced emulation. SBW is the default production-debug interface, requiring only two pins and providing full flash programming, real-time debugging, and register access without impacting application I/O resources.
